What is DNA?And structure of DNA.
Answers
Explanation:
DNA is a group of molecules that is responsible for carrying and transmitting the hereditary materials or the genetic instructions from parents to offsprings.”DNA Structure
The DNA structure can be thought of like a twisted ladder. This structure is described as a double-helix, as illustrated in the figure above. It is a nucleic acid, and all nucleic acids are made up of nucleotides.The DNA molecule is composed of materials called nucleotides, and each nucleotide is composed of three different components such as sugar, phosphate groups, and nitrogen bases.
The basic building blocks of DNA are nucleotides, which are composed of a carbon-sugar group, a phosphate group, and a nitrogen base. The sugar and phosphate groups link the nucleotides together to form each strand of DNA. Adenine (A), Thymine (T), Guanine (G) and Cytosine (C) are four types of nitrogen bases.
These 4 Nitrogenous bases pair together in the following way: A with T, and C with G. These base pairs are essential for the DNA’s double helix structure, which resembles a twisted ladder.
The order of the nitrogenous bases determines the genetic code or the DNA’s instructions.

hey mate here is your answer...
DNA: Deoxyribonucleic acid
It is a molecule composed of two polynucletide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acids are nucleic acids ...
